China 22kw OBC Charger Suppliers, Manufacturers - Factory Direct Price

Product Details

The SW-AS22000 series OBC (On-Board Charger) is specifically designed for larger power charger applications, such as buses and commercial trucks. It features a three-phase AC input and a wide output voltage range of 400VDC to 850VDC. The OBC is built to withstand harsh environments, including vibration, thermal shock, and extreme temperature ranges.

One of the notable features of the SW-AS22000 series is its liquid cooling system, which helps dissipate heat efficiently and ensures optimal performance. The OBC also comes with an IP67 enclosure, providing protection against dust and water ingress.

The OBC is programmable, thanks to the independent control unit embedded inside. This flexibility allows the charger to be customized to meet individual customer requirements. Additionally, the SW-AS22000 series has excellent multi-grid adaptability, making it compliant with international standards such as SAE J1772 and EN61851.

The 22kw OBC charger utilizes processor-driven charging algorithms, which optimize charging efficiency and contribute to a longer lifespan for both the battery charger and the high-voltage (HV) battery. These algorithms ensure that the charging process is tailored to the specific characteristics of the battery being charged, maximizing its performance and longevity.

In terms of application range, the PCHG-AS22000 series, manufactured by STARWELL, supports various battery types. This includes lead-acid batteries, lithium-ion batteries, ternary lithium-ion batteries, and lithium iron phosphate batteries. The 22kw OBC charger is specifically designed to charge these battery types effectively and safely.

Furthermore, the SW-AS22000 series supports communication via the CAN BUS protocol, allowing it to integrate with other vehicle systems for enhanced control and monitoring capabilities.
